Determination of serum and gingival crevicular fluid levels of omentin in healthy and rheumatoid arthritis subjects with and without periodontitis.

The omentin level in serum and GCF was found to be lower in RA patients with periodontitis. It is also inversely correlated with the periodontal parameters. Thus, omentin can serve as a significant diagnostic and therapeutic tool in both periodontal and rheumatoid disease.
